What not to do when you are singing?

When singing, avoid straining your voice by pushing too hard or forcing high notes, as this can lead to vocal damage. Don't neglect proper warm-ups, as they are essential for preparing your vocal cords. Additionally, refrain from singing in an uncomfortable posture, as it can hinder breath support and vocal projection. Lastly, avoid over-relying on vibrato or excessive embellishments, which can detract from the clarity of your performance.
